- Hitherto, when? the filamentslof artificial silk have issuedifromthe spinneret, they have ample, the di tficulty presented in determin ing just which way the-skein of-yarn; was wound as it'issuedfrom the spinning machine. During the intermediate treatment,

the 'yarn' .skeins Y are usually twis'tedEl andv moved into p osit'ions which make :it: difficult tolxdetermine at once: which portion of'the skein was inside, and which was outside when p v the yarngwas removed from the collector'vai' the spinning machine. 7, Furthermore, when thefskeins arejplacedon Swifts preliminary to winding: onto bobbins, it 1 was impossible to tell, definitely, just whiohz way the skein would unwind Ordinarilyflheegirl operating the swifts straightensout thelskeins to the best of her ability, andrthen places them upon theswifts. ,Many times,' the skeiniS ,SO-

thread when the winding is Completed. This last. danger arises from the "fact that there is no-way'by which the operator may.
